- The selected points must be visible on the canvas. You will need to draw a **small** circle surrounding each point.

- If the canvas has control points drawn on it, then pressing `Enter` should start the animation. It should cycle through the steps until reaching the 7th step of `Chaikin's` algorithm. The animation should then restart.
